Eugenol, Isoeugenol, Thymol, Carvacrol, and Ester Derivatives as an Ecofriendly Option to Control Glomerella Leaf Spot and Bitter Rot on Apple.

Glomerella leaf spot (GLS) and bitter rot (BR) are severe diseases of apple. and are the main species in Brazil. To control GLS and BR in Brazilian apple orchards, mancozeb and thiophanate-methyl fungicides are still used despite reported resistance to these active ingredients.

Development, characterization and antimicrobial activity of sodium dodecyl sulfate-polysaccharides capsules containing eugenol.

This work describes the production of polysaccharide multilayer capsules to control the release of Eugenol (Eug) and enabling its use as an antimicrobial agent. For this propose, oil-in-water nanoemulsions of sodium dodecyl sulfate were coated with alternating depositions of chitosan and carboxymethylcellulose using the Layer-by-Layer (LbL) technique, resulting in capsules containing 1-5 layers. The average size ranged from 188 ± 30 (LbL) to 1415 ± 517 nm (LbL).
